I'm a senior software engineer with over 20 years' experience building systems for major financial institutions, including JPMorgan Chase, Credit Suisse, and Morgan Stanley. My background spans Java, Python, and — more recently — applied AI/LLM and agentic engineering, including designing and deploying production GenAI tools and MCP server architectures.  I hold Oracle Java certification alongside five AWS certifications (including AWS Certified Generative AI Developer – Professional and AWS Certified Solutions Architect – Professional) and the FRM (Financial Risk Manager) designation, so I understand both the technical depth of the material and what it actually takes to prepare for and pass a rigorous certification exam.  My Java 25 mock exam questions are written and verified the way I'd want to study myself: compile-and-run checked against a real JDK, covering the full breadth of the exam syllabus, with clear explanations for every answer. Outside of my day job, I build and maintain several open-source Python and Java projects, including an MCP server built on Spring Boot and Java 25.
